AIS 2005/2008 Update Dictionary - Clarification Document

Updated: 10/9/2019 15:16

We have combined and revised the clarification documents into an Excel file that has been saved as a PDF for viewing.

The first section is this "read me" area followed by: ALL of the combined items; General; Definitions; Rules-Guidelines; Head; Face; Neck; Thorax; Abdomen; Spine; Upper Extremity; Lower Extremity; External; Other; Chart/Tables.

Although this is a PDF, you are still able to search the document.

We would like to take this opportunity to thank the AIS Faculty who worked on the development of the clarification documents over the years as well as those of you using the coding system for your continued support, questions and suggestions!

they do not specify its severity."

Superficial penetrating injury skin/subcutaneous/muscle only without

underlying organ or bony involvement. For penetrating injuries to the

extremities that do not involve bone or vascular structures, code as minor

injury.

Asphyxia definition is a condition arising when the body is deprived of oxygen, causing unconsciousness or death. This is a codeable sequela. (p.166)

Hemarthrosis is not a codable injury. Within the first 24 hours post injury, patients with transient signs and symptoms should be coded even if they are resolved within the 24 hour period.

(p.40)

Supratentorial codes to Cerebrum; Interpeduncular fossa (cistern) basal

cisterns code as injury involving hemorrhage in the brainstem; "Along" the

tentorium, code to supratentorial = Cerebrum.

(p.41)

One symptom that can exist without a closed head injury, no AIS code.

Occipital condyles are coded to the skull base.

(p.49)

Concussion must be documented in the medical record by a physician or

physician extender. Recorded in PI minutes is inadequate.

For codes with coma modifiers, "not associated with coma..." = means

there was documentation of coma, but it was not greater than 6 hours in

duration. "Associated with coma...." = means there was documentation of

coma, and it was greater than 6 hours in duration. The NFS code should e.g. SAH with coma 8 hours =

be used when there is no documentation of coma with an injury that has a 140695.3 SAH associated with

coma modifier.

coma > 6 hours

"LeFort" must be specified in the medical documentation to use the LeFort fracture codes, otherwise, code individual fractured bones.

Soft palate perforation code as laceration; hard palate perforation code as fracture. If palate is not specified as soft or hard, code as fracture.

Carotid Artery injury not specified should be coded to Common Carotid

Artery.

(p.66)

Jugular Vein injury not specified should be coded to Internal Jugular Vein. Within the first 24 hours post injury, patients with transient signs and symptoms should be coded even if they are resolved within the 24 hour period.

Rotator cuff should be assigned to Shoulder, Glenohumeral Joint, NFS

(p.121)

Skin tears are coded as a laceration to the appropriate location on the patient and assigned to the ISS body region for calculating an ISS.

Hanging/Drowning deaths with medical examiner's diagnosis counts as

"cardiac arrest documented by medical personnel".

Puncture wound is caused by spearing or impalement type injuries. These should be coded as Penetrating NFS or Penetrating minor superficial

Palsy/Paresis are coded as nerve contusion.

Paralysis or Total Loss of Function is coded as nerve laceration. Incomplete transection is the same as incomplete circumferential involvement.

Pseudoaneurysm is coded as a minor artery laceration.

REFERENCE/EXAMPLE

Amputation is defined as "traumatic" not surgical

Morel Lavalle Lesion , internal shearing or degloving injury of an extremity is coded as a degloving injury in the appropriate extremity chapter.

Micro fractures are not a codeable injuries.

Bone contusions are not a codeable injuries.

Bone edema is not a codeable injury.

Extra-Articular refers to a fracture with NO joint involvement. Partial Articular (Intra-Articular) refers to at least one fracture through the joint surface and part of the articular surface is still in continuity with the diaphysis.

Complete Articular refers to a fracture where the articular surface is fractured AND there is no continuity with the diaphysis.

Refer to drawings in the upper and lower extremity chapters Refer to drawings in the upper and lower extremity chapters

If the clinician does not differentiate and document the acute from chronic bleed, code as NFS in the appropriate section.

Pterygoid Plates are part of the sphenoid bone and are coded to the base of the skull if injured in isolation. If the pterygoid plates are part of a LeFort fracture, they are NOT coded additionally as skull base fractures.

Caustic injury to the mouth is coded as 243099.1 Thrombosis (occlusion) secondary to trauma from any lesion but laceration (under carotid artery, internal, and external, and vertebral artery) refers to the sequela of blunt trauma to neck. Spinal cord injury such as compression, epidural or subdural hemorrhage associated with a fracture AND there is NO neurologic deficit, the coder must choose to either code the cord injury OR the fracture. Current rules prohibit coding both.

(p.58) Example: seatbelt injury

Pars interarticularis is located between the lamina and the pedicle

anatomically and should be coded as pedicle. Previous teaching of coding

this to LAMINA has been changed per recent Neurosurgery input.

Persistent Air Leak (442203.4) is described as an air leak in the thorax

that lasts for more than 48 hours, which represents a more severe injury

than a simple pneumothorax.

Intracardiac Septum may also be identified as "intraventricular" septum. (p.78)

Flail chest with additional but separate rib fractures on the same

side is coded to the more severe injury, the flail chest, and the additional

rib fractures on the same side are not coded.

Hemoperitoneum is a sequela and is not a codeable injury.

"Hip Fracture" simply stated with no other description is coded as a proximal femur fracture (853111.3)

Slipped Epiphysis in children is coded as a femur neck fracture (853161.3)

Caustic injury (040099.9) is only used if the specific location is not known.

Vessel dissection should be coded to intimal tear for all vessels including descriptors for carotid artery common/internal, carotid artery external and vertebral artery.

May refer to either AIS Head or Neck Chapters . AIS Head codes 121099.3 to 121006.3 "Internal Carotid Artery" and 320099.9 to 320223.4 "Carotid Artery". When the exact location of the injury is not specified as to head or neck, code to the neck region with applicable associated detail (laceration, thrombosis, occlusion, etc.)

See also Face Chapter which includes branches of the external carotid artery.

May refer to either AIS Head or Neck Chapters. When the exact location of the injury is not specified as to head or neck, code to the neck region with applicable associated detail (laceration, thrombosis, occlusion, etc.)

When multiple small (140640.4) or large (140648.5) hematomas OR when

multiple small (140652.4) or large (140656.5) SDH are diagnosed, code e.g. 2 codes would be required

each individually IF they are separate and individual hematomas/bleeds of Small (L) frontal SDH = 140652.4

the same (unilateral) hemisphere. If both hemispheres are involved use Small (L) occipital SDH =
